PROBLEM TO BE SOLVED: To obtain a vinyl chloride-based resin composition having improved impact strength while keeping tensile strength, heat resistance, etc., by adding a specific amount of potassium titanate whiskers to a vinyl chloride-based resin or a chlorinated vinyl chloride-based resin. SOLUTION: This resin composition not inducing thermal decomposition (burning) of the resin due to an overheat in a molding is obtained by adding 1-10 pts.wt. of potassium titanate whiskers (e.g. 6- or 8-potassium titanate whiskers having 10-20μm average fiber length, 0.3-0.6μm average fiber diameter, about 7 GPa tensile strength and about 280 GPa tensile elastic modulus) to 100 pts.wt. of a vinyl chloride-based resin (e.g. a homopolymer or a copolymer with an olefin or vinyl monomers) or a chlorinated vinyl chloride-based resin.
